Description
The type defines the format in which the card alias is
sent to the gatekeeper. Each alias can be of a
different type:
•
H.323 ID (alphanumeric ID)
•
E.164 (digits 0-9, * #)
•
URL ID (URL style address)
•
Transport ID (IP address: port number)
•
Email ID (email address format)
•
Party Number (identical to the E.164 format)
Note: Although all types are supported, the type of
alias to be used depends on your gatekeeper's
capabilities.
